It is designed to monitor the open and closed position of overhead doors, providing a reliable electrical signal to alarm panels, access control systems, or automation controllers. The DPDT contact arrangement gives installers flexibility to wire both normally open and normally closed circuits simultaneously from a single device. Security and low-voltage systems technicians typically install this switch as part of a door monitoring or intrusion detection circuit.\u003c\/p\u003e\n\u003cp\u003eThis switch is suited for commercial and industrial overhead door applications where a compact, discreet form factor is required. It mounts directly to the door frame or header and actuates as the door travels. Common installation scenarios include loading dock doors, warehouse roll-up doors, and commercial garage doors where position feedback is needed for security or automation systems. The DPDT output makes it adaptable to a wide range of control panel input requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-pole double-throw (DPDT) contact configuration for simultaneous NO and NC circuit wiring\u003c\/li\u003e\n  \u003cli\u003eMiniature form factor suited for low-profile overhead door frame mounting\u003c\/li\u003e\n  \u003cli\u003eDesigned for overhead door position monitoring in security and access control applications\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging for straightforward one-for-one replacement or new installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation switch for overhead door monitoring circuits used in commercial and industrial security and access control systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed low-voltage or security systems technician. Disconnect and de-energize the alarm panel or control circuit before wiring the switch. Mount the switch to a fixed surface on the door frame and position the actuating magnet or trigger on the door leaf so contact changes state fully at both the open and closed positions. Follow all applicable local electrical codes and manufacturer wiring diagrams when terminating DPDT contacts to the control panel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: Double-Pole Double-Throw (DPDT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Mini Overhead Door Switch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: George Risk Industries Inc.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4532D-36\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GEORGE RISK INDUSTRIES INC.","offers":[{"title":"Default Title","offer_id":51686915965234,"sku":"4532D-36","price":104.79,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/george-risk-industries-4532d-36-mini-overhead-door-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
